Using the Water Worm Water Sensor is a breeze. Just place it in areas where water leaks might occur, like near sinks or under appliances. When it senses water, it'll do its job to alert you. Keep it away from direct sunlight and extreme temperatures to maintain its performance. To clean it, simply use a dry cloth. Don't submerge it in water or use harsh chemicals. With proper care, this sensor will serve you well for a long time.
